Hi Guys,
Finally i had time to try the NVidia Web drivers on my iMac8,1 with my NVidia 9600m GT but it did same, still a black screen.
Any other idea?
I'm about to buy a display port adapter to test if the video card send a signal. Maybe the video card and the screen doesn't know how to talk together ;-)
Is there a way to be sure the drivers are loaded for my GPU?
Thanks.
Josh.

Hi Guys,
Thanks for answering and for the good ideas!
Just need to figure out how to change my model from iMac to MacPro cause this drivers only want to install on MacPro systems or maybe i can use "Pacifist" to do the job.
Anyway i have moutain lion as System Os but upgraded to 10.8.4 now so i need to wait the new drivers from Nvidia.
Thanks.
Josh.

Some news...
I've activated Apple Remote Desktop and i can connect to it.
The good news is that the system detects the Graphic Card correctly.
Here is the screenshot :
I tried NVenabler but it looks like i get KP.
As i have the right informations in "system information", do i still need to look into Enabler like ATY init or NVenable or the problem is elsewhere?
Here is the bios of my card if someone knows what to do... http://www.techpowerup.com/vgabios/57025/nvidia-9600mgt-1024-081007.html
Also, i looked to this thread http://forum.netkas....pic,490.75.html and i'm a bit hopeless to solve my problem now...
Thanks.

Hi Guys,
It has been a long time...
I bought a dead iMac 20 early 2008 with a defected Ati Radeon HD 2600 Pro.
I've seen on ifixit that some people were pretending this card can be replaced with a Nvidia 8800m GS or even with a MXM II graphic card specifications. So i decided to buy a Nvidia 9600M GT with same specs. Here it is : http://www.ebay.com/itm/280924092840?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
But it did not worked for me. I replaced the card one time, boot the Mac, heard the dong but black screen (Target mode working). So i decided to put back the defected one to see if the Logic Board had something to do with it and i could see the screen showing up.
So, i guess, it could be a defected 9600M GT or an uncompatible card for the iMac...
Do you know if i can flash the graphic card so the iMac will accept it?
Any other idea?
If any Guru knows, that would be cool! ;-)
Thanks!

Hi Guys,
There is a new graphic update that i installed without any problems.
I wish that it will solve the HDMI output problem.
Can someone test it as i didn't have my HDMI cable anymore ?
Thanks.
Josh.

Hi AB,
In fact, after trying the last version of Chameleon from mozodojo (rev 238) and using fakesmc from Slice rev 384, i'm still getting lpc errors that had disseapered from my boot logs for some hours... too bad.
Here is the screenshot of the istat showing many temps monitor with the last fakesmc kext from Slice :
@oSxFr33k,
What revision of Mozodojo Chameleon are using to get lpc warning away?
Could you post it?
Any other advice?
Thanks for all your work!
Julien.

Cool News!
Great job, especially Slice!
Thanks to oSxFr33k and Thanks to all!
How can we be sure that C-States is working?
I tried this command i found on an osx86 site but it did not report anything as it should :
sudo ioreg -lw0 | grep CSTInfo
I now don't have the lpc warning and istat is showing the cpu, hd and gpu temps.
Any advice?

Hi all,
So finally that was it!
With my new motherboard, no more hands/fingers hurts... ;-)
My Pc temp's are now normal and values are quiet the same as Brett's ones.
So Thanks a lot!
That was a good info!
Have a nice day all.
... And check the Netkas blog, Slice and others has done a good work (regarding monitoring temps...)
Julien.

Hi Immo, Hi Brett
Thanks to you two, i finally called Dell as my Pc was still under waranty.
A technician come on monday to replace the motherboard.
Thanks a lot guy. Good to talk to you as you always gave us good advices.
Have a good weekend.
Cheers
Julien.

Hi Immo,
I finally register Coolbook and you were right, i was able to choose the cpu frequency i wanted.
Here are the temperatures my Pc is having under Osx :
CPU 1 :52
CPU 2 :52
HD :45
I can't see the GPU temp, is that normal?
I guess there is a sensor for the Gpu too but i've tried istat and temperature monitor and both were not able to see the gpu temp...
I find the Pc temp still too high even running at 800Mhz and i starting thinking like you about a gpu issue.
I will try your gpu trick first.
Thanks.
